12/8/2023 0 Comments Sentinel node dissectionIn the past, a lab test called immunohistochemistry (IHC) was sometimes used to assess lymph node status. The most common way to assess pathologic lymph node status is a lab test called H&E staining. If you have a positive sentinel lymph node, talk with your health care team about whether you need an axillary dissection. Most people with one or more positive sentinel nodes who have a mastectomy will need an axillary dissection or radiation therapy to the axillary lymph nodes. (Whole breast radiation therapy treats part of the underarm area as well as the breast.) Some women with 1-2 positive sentinel nodes who have a lumpectomy and will have whole breast radiation therapy may not need axillary dissection. The goals of axillary dissection are to check how many lymph nodes have cancer and to reduce the chances of cancer returning in the lymph nodes. More lymph nodes may be removed with a procedure called axillary dissection.
